Does anybody know the specifics on the "up to 1GB" for storage of the Forge? Does it mean that if I get a 1GB SD card, the total memory recognized is going to be 1GB whether I have the 126MB, 256MB, or 512MB Forge? Is there a chance that a future firmware update could change the max amount of storage (say, if someday 2GB SD cards are available for a reasonable price)?
